Understanding Inspection Pass Rate
How we calculate. Pass % = inspections passed ÷ inspections performed × 100. See our methodology and accuracy policy .
Real-world scenario: A typical Inspection Pass Rate case uses passed inspections 88 and total inspections 100. Enter the same figures below to reproduce the worked path.
What is Inspection Pass Rate?
A QC readiness KPI. Distinct from punch-list completion, which tracks deficiency close-out after inspection findings.
- Same inspection set
- Pass = accepted without re-inspection per policy
- Segment by trade
The Formula
Worked Example
Common Use Cases
- ITP tracking: first-time quality
- Trade scorecards: re-inspection load
- Owner QA: inspection health
Pro Tips
- Don’t count waived holds as passes unless labeled
- Track fail reasons
- Pair with punch list completion
| Scenario | When to use |
|---|---|
| Percent of a number | Finding a part of a whole (tax, tip, score) |
| Percent change | Comparing old vs new values |
Limitations: Inspection Pass Rate results are educational construction planning aids—not engineering, safety, legal, or cost-estimating advice. Confirm definitions with your project controls, safety, and contract documents. For earned-value SPI/CPI see the Professional hub.
Common mistakes
- Swapping part and whole: The denominator must be the full total, not a subset.
- Rounding too early: Carry extra decimal places through multi-step work before rounding the final percent.
- Mixing percent and decimal forms: Enter rates in the format the calculator labels expect.
